> Please post an example where its doesn't work, so that we can fix it.

Note: I'm trying this in a mobile browser (Firefox).

- Search for a word 'Decentralized'

- pick the second result: 'A decentralized web would give power back to the people online'

- On the result's (preview?) page, click the tag 'Decentralization'

I get no response, nothing updates, no new tab opens. Not sure what is the intended action (I'd assume it should be a new set of results corresp. to the hashtag). Same issue with 'google' example that you described.
